VALVE-PROTE'GFQR.

and useful Valve-Protector, of which the fol-.

lowing is a specification.

. This invention relates to improvements in valves for condensers, pumps, and the like.

The principal object is to-provide a novel protector for the valve member, said rotector bein a simple article of manu acture which wi l eliminate the wearing of the valve by the spring and guide-stud and providing an elongated bearing for said stud in order to procure an easier action for the valve, said protector, moreover, being associated with the valve in'such a manner that it will not materially interfere with the resilience and pro er seating ualities thereof. I

T e referre embodiment of the invention is i lustrated in the accompanying drawings, Wherein- Figure 1 is a side elevation of the valve and its mounting. Fig. 2 is a sectional view therethrough. Fig. 3 is. a detail perspective view of the protector.

Similar reference-numerals designate corresponding partsin all-the figures of the drawings. I

In the embodiment illustrated a valve-seat 4 is'iemployedhaving a spider: 5, provided with a central boss 6, in which is threaded the usualguide-stud 7 Coo erating with the galve-seat is a valve 8, slid the stud and comprising a rubber or yielding disk having a central opening 9, through which .the stud 7 passes, being furthermore provided on its outer side-With annular ribs 10, concentric to the opening. r

The outer side of the said discal body is provided with an integral outstanding conical projection 12, which is'hollow, said rojection carrying an integral collar 13, whic collar extends axially beyond the side of the body 11 o posite to the said projection 12., 'A's'ayres t an annular groove or seat 14 isform d in the inner side of the protector body11j, said seat receiving the. inner annularrib 1}) of the valve 8, the

of the valve. I The protector, furthermore, as

it terminates short of theifouter' margins ,of.

the valve does not materially-interfere with the yieldin action andproper seating qualities therec Experience has demonstrated that the valves which have heretofore been discarded as worn out can be remployed in connection with the'protector and will oper-' etc as satisfactorily as new valves. Conseuentl it will be a parent that the lives of t e va ves are great y prolonged. A From'the foregoing it is t ought thatthe construction, operatlon, and 'many advantages of the herein-described invention will be a parenttothose-skilled in the art withther description, and it be under stood that various changesin the size, shape,

out,

proportion, and minor details of construction may be resorted to without'ldeparting from the spirit or sacrificing any of the advantages ofthe invention.

' Having thus described 'my invention, what 7 .I claim as new, and desire to secure by ,ters Patents-is j i 1. As an article'off manufacture, a valveprote'ctor comprising aspring-vabutment disk 5 I 7 ody having 1 an outstanding centrallyedise posed conical projectionon one side and a .iod guide-collar prei'ecting from'the opposite ,.if side, said comca projection and collar. have ing a commonfiboreto reeeivea guide-stud edto vide'd with an annular valve'rribereceivmg groove or seat that surrounds the collar and extends into the conical pro ection.

22. In a valve-protector,the combination with a valve-seat, of a guide-stud projecting therefrom, a yielding valve cooperating, With the seat and having an opening through which the annular ing, a protector comprising a discal body ar ranged against the cent all oinstanding hollow conical projection oarried hythe outer side of the dish, a guidecollar carried by jection and extending beyond the inner side of the disk, said projection and collar surstud passes, said valve having an rih on its outer side around the openouter side of the valve a the inner portion of the provalve engaging rounding the guidestud and constituting an elongated bearin therefor, and said collar fitting in the valve-opening and the rib of the in the hollow portion of the conical projection, and a spring mounted on the stud, said spring surrounding the conical projection and hearing against the ontersido of the protector-body.

In testimony that 1 claim the foregoing as my own I have hereto allixed my signature in the presence of two Witnesses.
